, Application filed January 12, 1920'. Serial No. 350,777.

T all to 700m it may concern Be it known that 1, lnzzrn Hnrznn DIOK- ELMAN', a citizen of the United States, and a resident of Forest, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Doors and Door Frames for Grain Bins, of which the following is a specification.

My invention relates to improvements 1n grain storage bins, it being more particularlyyan improvement in the door and door frame structure, and it consists in the constructions, combinations and arrangements herein described and claimed.

, One of the foremost objects of my invention is to provide means whereby a corru-' gated door can be made to fit tight in the opening of a corrugated grain bin so as to prevent the entry of mice and the leakage of grain. I

if further object of the invention 1s to provide a drip or watertable which extends out beyond the door frame over thetop and at the sides of the opening, to prevent the water running down on the inside of the grain bin at the door.

A further object of theinvention is to provide improved door facings which are so bent as to produce the requisite rigidity and strength, doing, away with the use of angle iron braces and thereby making the door light, at the same time preventing it from buckling or warping.

A further object of the invention is to provide .a rat and mouse-proof door frame for grain bins, this frame being particularly adaptable for use in wooden grain bins which have been covered with metal building plates, the usev of such, metal building plates and the herein described improved door frame enabling the conversion of wooden grain bins into lire, rat and mouseproof bins.

Other objects and advantages will appear in the following specification,. reference being had to the accompanying drawings, in

which Figure 1 is an elevation. of the improved metallic door frame, showing thedoor closed in the opening, I

Figure 10 is a detail view of the upper portion of one of the facing plates,showing' how it is stamped out before crimping, and Figure 11 is a similarview, illustrating the facing plate after crimping, to form the inner strengthening rib. I I

In Figure 1, the parts '1, 2 and 3 are portions of the horizontally corrugated plates of a sheet metal grain bin. These plates are so arranged as to leave an opening 0 in Figure 2, in which theimproved fire, water, rat and mouse-proof door frame and door is fitted.

The construction is more easily understood by considering each of the parts of the frame in order, and attention is therefore directed to the side or jamb plates 4:, 5. Each of these I is precisely alike, so that the description of one will suflice for both. The jamb plate 4, for-example, is made of sheet metal, bent at 6 to provide a vertical channel for the reception of the grain boards 7, which are inserted or taken out, as the bin is filled or emptied of grain, very muchon the order of the removable boards of an ordinary coal bin.

The inwardly bent portion 8 fits behind the wall2, to which it is secured by the means 9 and forms a perfectly tight joint through the provision of thebent ridge 10, which abuts and closes the openings which would otherwise be left by the corrugations of the plate 2. The inner extremity of the jamb plate 4 is bent upon itself at 11, to provide a rounded edge. Secured by certain of the fastening means 9 and other means 12, is a plurality of hasps 13, preferably three in number.

In these the cooperating latches 14 of the door are secured, when the door is closed in the opening 0 against that portion of the Specification of Letters Patent. Patented June 13, 192g wardly,

' nel 25 are cut away jamb plate between the rounded edge 11 and the rib 10. The three latches shown are pivoted to the corrugated body of the door at 15, and are connected by a common bar 16 with a handle 17, by means of which all three latches are lifted at once, and similarly closed. .1 A padlock 18 secured to one of the hasps 13 and a companion hasp or wear plate 19 on the door, locks the door whenclosed. I

The lintel structure comprises the horizontal plate 20, with bent flanges 21 at the ends, and 22 at the back, the front corners being cut out at 23 to leave a front lip 24: to fit into the channel 25 of the vertical plate 26. The channel 25 provides a drip plate or water table over which the water runs in the direction of the arrow in Figure 5.

This channel or water table extends foras clearly shown in Figure 5, and also laterally beyond the edges of the door opening, so as to carry the water well beyondthe place where the opening comes and thus prevent theentrance of such water into the door opening. The inner corners of the chanat 27' for a length approximately equal to thecorresponding part ofthe cut-outs 23 of the horizontal plate 20, the remaining portion ofthe channel being bent down to form the .top jamb flange 28 i a hinged at35. by hinges of any suitable typewhich the upper part of the door abuts when closed.

.Qn ,fitting the horizontal and vertical plates 20, 26 together asin Figure 9, a narrow space 29 is left at each extremity where the cut-out portions .come together, this space being occupied by the upper part of each side plate 2, 3. This arrangementprovides a satisfactory; joint] or connection, and is found to well exclude rats and micebecause of its closeness. The end flanges 21 of the plate 20 overlap the vertical edges of the side jamb plates 4, 5,'where they are secured by the means 30 in Figure 5. The upper plate 1 overlaps the vertical'plate 26, where it is secured by the means 31, in Figures 1, 2 and 5. The sill plate 32 consists simply of a strip of metal, crimped or bent upon itself to form the horizontal rib 33 over which the lower edgeof the door closes. The water runs off of the door in the direction of the arrow in Figure 6, and down over the rib 33. The sill plate secured at the extremities by the means 3a, to the adjacent portions 11 of the vertical j amb plates, and theprojecting rib or flange closes the opening in such away as to make the door absolutely mouse-proof.

The door consists of corrugated metal so as to correspond to the plates 2, 3. The door is The latch mechanism has already been described in connection with the structure shown in Figure 1. q v 9 p -Attention is directed to the particular cone structioniof the facingplatesBG.onthe.ver- 5 tical edges of the door. These consist originally of plain sheets of metal, the upper portions of which are stamped out as in Figure 10, toproduce an opening 37 and leave adjacent tongues and recesses. The plate is. then c'rimped longitudinally, or brought together in such a way as to pro duce the rib 38. This rib adds the requisite strength to the facing plate, and takes the place of the angle or other shaped irons usually employed for strengthening PHI-1 poses.

WVhen the plate 36 is crimped longitudinally as described, the various tongues and recesses shown in Figure 10, come together as in Figure 11 so as to form a closure. Substantially the same arrangement of cutting out, is followed in respect to the bottom end of each plate, the sole purpose. of thus cutting out the ends of the plate being to close the plate at the top and bottom and provide a continuous contacting surface against the upper and lower jamb and sill flanges 28, 32. As shown in Figure 4, the facing plate is secured at 39 and bent around the edge of the door at 40 to provide a smooth closed edge adjacent to the rib 10 of the frame structure.

The manner of application of the improved door frame and door is simply to fit the frame in an opening properly provided, the securing means 9 holding the frame in place. An important advantage arises from thecapability of using the frame and door on old wooden grain bins. Such bins could be covered with certain ventilating metal building plate, and when so covered and provided with the improved door frame and door, makes a grain bin which is proof against the inroad of all kinds of vermin, and the entrance of water and fire.

While the construction and arrangementof the improved door frame and door, as herein described and claimed, is that of a generally preferred form, obviously modifications and changes can be made without departing from the spirit of the invention or the scope of the claims.

I claim a 1. A storage bin including plates arranged to leave an opening, a door frame comprising jamb plates secured behind the vertical opening edges, with j amb ribs in the opening, and inwardly extending flanges; a sill plate at the bottom, with a water shedding rib in line with the jamb ribs; a lintel structure including a horizontal top plate with end flanges secured to the jamb plates and cut out front corners leaving a front lip, a

vertical plate secured between plates of the leaving a space to receive adjacent bin plates; and a door hinged to close against said flanges within the confines of all ribs, including means for fastening it in the closed position.

2. Lintel structure in a sheet metal door frame, comprising a horizontal plate having bent flanges on the ends and back edge, the front corners bein out away,,to leave a front lip; and a vertical plate securable between overlapping metal plates of a storage bin, with a hen rib or channel to receive the lip, having cut away corners coinciding with the cut away corners of the horizontal plates to leave narrow plate-receiving space, the remainder of the vertical plates being bent down to form jamb flange.

3. Means for tightly fitting a door and frame into the opening of a corrugated-plate storage bin, comprising a sheet metal frame located behind the opening, with ribs and flanges extending thereinto, the vertical jamb ribs forming closures for the openings of the corrugations of said plates; and a corrugated plate door, hinged to close against said flanges within the confines of said ribs, having facing plates secured and bent over the vertical edges to close the corrugations, and including ribs bent up for strengthto avoid the use of other strengthening means.

4L. A facing plate for a corrugated sheet door, comprising a metallic plate with spaces at the upper and lower ends stamped out to leave corresponding tongues and recesses, formed with a longitudinal strengthening rib whereupon said tongues and spaces fit together, and secured and bent over the vertical edge of a door to close the opening left by the corrugations.

5. A storage bin door, comprising a frame with vertical jamb plates having opposing bent channels for receiving grain boards, inwardly bent portions to lie against the inside of a storage bin adjacent an opening, and a forwardly bent ridge in each bent portion extending into said opening to close the otherwise open ends of the horizontal bin corrugations.

6. 'A storage bin door, comprising a metal door frame bent to produce ribs contacting all sides of a bin opening and thus close the otherwise open ends of horizontal bin corrugations, including flanges extending inwardly in respect to the opening, and a door located within the confines of said ribs when closed in contact with said flanges.
